Appetite stimulants are the common treatment for cancer-induced anorexia. However, only 30% of advanced cancer patients respond and benefit from appetite stimulants, which may be due in part to sensory abnormalities, as a person who is experiencing food aversion due to taste and smell changes may be unable to respond to these agents. Of the appetite stimulants available for use in clinical practice only Marinol, or THC, has the potential to increase food intake by improving appetite as well as by amplifying the taste of food through the brain's reward pathway.
